Up to February, 2013, I have not found any other than Fedora, to support UEFI boot mode, out of the box, all the other ones, Ubuntu, Debian, kubuntu, Linux Mint, etc. All need to have the kernel recompiled with extra settings and parameters in order to add the UEFI functionality.

Even if you do that, it will not detect automatically what type of boot mode there is, the kernel will just be recompiled for UEFI.
